With their touch-sensitive response, SABIAN 13" HHX Evolution Hi-Hats deliver glassy, shimmering responses, and project even the busiest sticking with crisp clarity. Until HHX, it was impossible to project darkness. But the dark, simmering sound, agitated bite and "Tone Projection" design of HHX makes this series more effective than others. Other cymbals may generate darkness, but HHX stirs up more simmering heat, more musical dirt, more of what drummers want to hear – and projects it. It gets you heard. And felt. HHX "Tone Projection" is an innovative design, created by the SABIAN Vault team.
